Player error
Map player error is detected.
1. Check if the disc can be inserted
and ejected. If a malfunction is
found, replace the radio and nav-
igation assy.

High temperature
High map player temperature is detected.
1. Park the vehicle in a cool place.
Turn the engine off. After check-
ing that the temperature of the
radio and navigation assy be-
comes sufficiently low, turn the
engine on to verify the malfunc-
tion symptom.
